Spark Technology Services Limited in Reading

About Spark Technology Services Limited’s Reading allocation

When Spark Technology Services Limited is the range holder for +44 118 it means Ofcom recorded Spark Technology Services Limited as the provider entitled to issue numbers from these blocks when they were first allocated under the UK National Telephone Numbering Plan. 1 Reading-facing block sits against Spark Technology Services Limited in the current Ofcom snapshot, each of which can carry up to ten thousand individual digits available for assignment to end customers.

Reading’s Thames Valley telecoms estate is shaped by Reading's catchment of roughly 318,000 residents: a dense urban exchange typically hosts allocations from several national operators in parallel, which is why you see Spark Technology Services Limited’s blocks alongside other range holders on the same 0118 code. Local switching capacity, historic Openreach exchange footprints, and Spark Technology Services Limited’s wholesale routing arrangements all influence which blocks land in Reading rather than elsewhere on the national plan.

Treat this allocation as a starting point, not a verdict on any specific caller. UK numbers are portable, so the current carrier on a given 0118 digit string may differ from the range holder shown — read Range Holder vs current provider for the distinction, and How Ofcom allocates UK phone numbers for the wider context behind the table below.
